Printed p-type single walled carbon nanotube (SWCNT) based circuits exhibit high power dissipation owing to their thick printed dielectric layers (>2 μm) and long channels (>100 μm). In order to reduce the static power dissipation of printed SWCNT-base circuits while maintaining the same printing conditions and channel lengths, complementary metal-oxide-semiconductor (CMOS) based circuits are m...

The intention of this research was to investigate the ink diffusion that takes place in dip-pen nanolithography in order to better understand how to enhance the possibilities of nano fountain probes. Varying concentrations of 16-mercaptohexadecanoic acid in ethanol were used as ink in dip-pen nanolithography, and the relationships between contact time, concentration, and ink diffusion were stud...

Original scientific paper A different number of white ink layers printed with the inkjet technology can influence the legibility of prints. Therefore, we tested how to achieve best legibility of printed text and labelling information, considering the changes in colorimetric and typographic properties. The prints were made with an inkjet printer and three different numbers of white ink layers we...

1. A behavioral and electrophysiological analysis of defensive ink release in Aplysia californica was performed to examine the response of this behavior and its underlying neural circuit to various-duration noxious stimuli. 2. Three separate behavioral protocols were employed using electrical shocks to the head as noxious stimuli to elicit ink release. Ink release was found to be selectively re...

Ink-jet microdispensing methods can be used to address a number of MEMS packaging challenges. Inkjet microdispensing is data-driven, non-contact, and is capable of precise deposition of picoliter volumes at high rates, even onto non-planar surfaces. Being data-driven, it is highly flexible and can be readily automated into manufacturing lines. It does not require application-specific tooling su...

A blue tattoo is more resistant to laser therapy than black or brown tattoos. This study aimed to confirm titanium as a key response-disturbing constituent in a blue tattoo ink after Nd-YAG (1064 nm) laser treatment by animal experiments. Rabbits' backs were tattooed with four ink colours, and the Nd-YAG (1064 nm) laser was used to remove the tattoos. The response to the laser treatment in the ...

A combined experimental and computational study of the transfer of transparent index-matched silica-particle inks between two flat plates is presented for gravure printing applications. The influence of printing speed and initial ink droplet size on the ability to accurately transfer ink during the printing process is explored systematically. Smooth interface volume of fluid simulations show th...

Problem 1. Assume the dimensions of an answer sheet to be 297 mm by 210 mm. Suppose that your pen leaks and makes some non-intersecting ink stains on the answer sheet. It turns out that the area of each ink stain does not exceed 1 mm. Moreover, any line parallel to an edge of the answer sheet intersects at most one ink stain. Prove that the total area of the ink stains is at most 253.5 mm. (You...
